[Soekris] net6501: Timer problems with Debian, no HPET support detected
Hi I tried Debian/Ubuntu with different kernels 2.6.32 and 2.6.38 on net6501-70 BIOS 1.41a. All do not detect the HPET. Kernel timer interrupt frequency is approx. 1000 Hz instead of 4000 Hz or higher with LowLatency kernel. Same kernels on other motherboards work fine. cat /proc/timer_list does not list hpet and shows .resolution: 999848 nsecs instead of 1 nsecs Any workaround?

[Soekris] net6501: Timer problems with Debian, no HPET support detected
Hi Frank Danke/Thanks. I found no option in Soekris BIOS to activate HPET. I installed always fresh OS (Ubuntu) with PXE netboot. I need 2.6.3x kernel because of own real-time kernel driver. I need high resolution timer with 4000 Hz. High resolution timer seams not work on Soekris net6501 because of missing HPET. On net6501 I only get pit and lapic but no hpet with cat /proc/timer_list. Reagrds George Hi George, perhaps you will do a list search for the following: Author: Wim Vandeputte Subject: [Soekris] net6501 - Linux 2.6.32-5-686 (Debian 2.6.32-35squeeze2) = 2 messages Author: Karl Auerbach Subject: [Soekris] Linux on Net6501 = 2 messages Is the bios from the Soekris net6501 ACPI conform? (If not shame on me) Did you first install on another machine (Hardware) the OS and put this medium (HDD/SSD) in the Soekris box? <http://www.vdr-wiki.de/wiki/index.php/ACPI_Wakeup> is written in German but declares the HEPT problematic on some hardware at the example with Debian Linux very fine and shows some main boards with and without support. Or have a quick look at <https://bugzilla.kernel.org/show_bug.cgi?id=12013> (English) Did this main board have special options for enable and disable the HPET in the bios and at the Soekris hardware this options should now be changed? Wim Vandeputte was using the Debian 6.0 kernel version - 2.6.32-5-686 for a test. Karl Auerbach: wrote >" I've now got Linux 3.0.8 up and running (in 32-bit mode) on the Net6501." >"I had to apply the patch below to fix the kernel panic problem." At some main boards HPET must be disabled by setting the kernel parameter hpet=disabled, it is not enough to discard this option during the kernel configuration, because the RTC driver does emulating a HPET device. I hope this was helping you out. -- Kind regards Frank >-Original Message- >From: soekris-tech-bounces at lists.soekris.com [mailto:soekris-tech- >bounces at lists.soekris.com] On Behalf Of George >Sent: Saturday, March 10, 2012 12:31 PM >To: soekris-tech at lists.soekris.com >Subject: [Soekris] net6501: Timer problems with Debian, no HPET support detected >>Hi >>I tried Debian/Ubuntu with different kernels 2.6.32 and 2.6.38 on >>net6501-70 BIOS 1.41a. >All do not detect the HPET. >>Kernel >timer interrupt frequency is approx. >1000 Hz instead of 4000 Hz or higher with >LowLatency kernel.

Re: [Soekris] net6501: Timer problems with Debian, no HPET support detected
Thank you Chris. I found no newer firmware than 1.41a on soekris downloads and I need a 2.6 kernel due to compatibility of own software (kernel driver).

Re: [Soekris] net 6501: soft boot
Yes, on console it says 12345 after soft boot and then it hangs. It,s a Transcend 16GB MLC mSATA from Soekris web-shop. Hopefully tested. Kind Regards George Sent by iPhone on the road.

[Soekris] net 6501: soft boot
I installed Ubuntu Linux 10.4 LTS on a mSATA/net6501. When I make soft reboot (sudo reboot) net6501 hangs after starting. Any idea? Thanks George ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
[Soekris] Problem updating bios on net5501.
Hi, I have my net5501 hooked up to a mac over USB. Console works fine but with minicom and with cu + sx I cannot seem to download a BIOS. Here is what happens: > download - Start sending file using XMODEM/CRC protocol. .. Error receiving file, aborting. here is what my console settings look like: ConSpeed = 9600 ConLock = Enabled ConMute = Disabled BIOSentry = Enabled PCIROMS = Enabled PXEBoot = Enabled FLASH = Primary BootDelay = 5 FastBoot = Disabled BootPartition = Disabled BootDrive = 80 81 F0 FF ShowPCI = Enabled Reset = Hard and yes I have turned of hardware and software flow control in minicom. Suggestions? Best, George ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
[Soekris] net5501 pins?
Hi, I cannot find a manual or a diagram that shows what the pins on the 5501 correspond to. Some things, like SATA, PATA are easy enough but I'd like to wire up the second serial port so I'll need to know where that is. A search of the archives and net didn't show me anything.
